We have a service which was built in PB 2017.  We have upgraded the service and deployed it to a new Windows Server VM.

When we try start the service, we get this error

I then checked in Event Viewer and the error is "Powerbuilder VM not found".

Any idea how we can get this error sorted?  The PowerBuilder 2021 run-time was installed on the server.

Hi Tanya;

  Is this an IIS web service or an O/S Service?

  Did you install the PB runtime via the "PB Packager" utility's created MSI?

Hi Tanya, You mentioned PB 2017 and then you mention PB 2021.  So it sounds like problem you are having is getting the PB 2021 version of your project to work?  If yes, please note that starting from PB 2019 R3, change was made to how the runtime deployment is handled.  Please carefully read this: https://docs.appeon.com/pb/whats_new/Separating_Runtime_from_IDE.html

Best regards,
Armeen

Q1:  Is this an IIS web service or an O/S Service?

O/S Service

Q2:    Did you install the PB runtime via the "PB Packager" utility's created MSI?

The PB packager utility to create the MSI package doesn't work on my laptop or my colleagues.  We were advised to install it by running the Powerbuilder Installer and selecting to install the run time package.

If the PB packager utility that created the MSI runtime package doesn't work - then you are having some significant O/S and/or environment issues.

My colleague's machine is a clean install of Windows 11 with Powerbuilder 2021 and he gets the same error as me. It just says "Compiling the MSI for PowerBuilder .NET runtime produces an error.

Hi Roland

To be very honest, that I am still trying to figure out.  I am a .Net developer not a Powerbuilder developer, so this is all new to me.  I just followed the installation guide created by the previous developer to install the service on the server and copied across the updated 2021 .pbd files for the service.

You can't create a Windows Service with just PowerBuilder. There must be some other tool involved. Do you know what that is?

Hi Roland



We use pbniserv to run it as a service. I actually wasn't aware this was a 3rd party tool.

The "pbniserv" 3d party tool could be the issue.

Thanks Armeen.

I did go through the documents previously, but not sure what I would need to change if anything.  We do have a registry setting for the service which specifies the name of the pbvm.dll.  I updated it from pbvm170.dll to just pbvm.dll, but it didn't help.

PB 2021 doesn't add the PB Runtime folder to the system path like PB 2017 did. You need to add the PB 2021 runtime folder to the system path.

The runtime path should be something like:

C:\Program Files (x86)\Appeon\Common\PowerBuilder\Runtime 21.0.0.1509

The runtime install created the folder you mentioned.
